I have a Dell Inspiron 1525. I upgraded the RAM to 4GB. I purchased a new 500 GB hard drive. I installed the Application disk, now I installed the Operating System disk and can not get anything to happen. Not even sure if anything installed. These are the disk that came with the purchase of the machine back in 2007. The machine came with the disk installed, so they have never been opened. What am I doing wrong??
